connectToSortable doesn't contain ui.item in callbacks

If you try to use the connectToSortable, callbacks registered to an event, such as receive or activate do not contain the ui.item element.

You can test this with the following code in tests/visual/sortable/sortable_massive_scale.html

$(function() {

var uls = $('ul').not(".draggable");

uls.sortable({ items: "li", connectWith: [uls], });

$("ul.draggable li").draggable({ helper: "clone", connectToSortable: "ul"});

uls.bind('sortablereceive', function(event, ui) {

console.log('sortablereceive', this, arguments, ui.item);

});

});
